' This invention relates to bedframes, and especially to a'novel type of a bedframe that has an improved caster receiving socket provided which is light in weight and one which can readilybe moved-about in the bedroom to facilitate making the bed and cleaning under it. Thus the frames are provided with casters which usually are of the type that trail or track and this simplifies and facilitates rolling the bedframes about in the bedroom. In a caster of this type it is necessary that the support axis of the caster be offset from the longitudinal axis of the caster leg by which the caster is supported. This oifset relation between the caster leg and the actual support shaft on which the caster wheel is journaled produces a turning moment of force which tends to pull the caster socket out of its original position. Hence in many instances bedframes of previous constructions have, under normal loads, permitted the caster receiving socket portions of the same to be bent or otherwise distorted due to the turning moment produced thereon when the bedframe is loaded. Also,'in previous types of bedframes, the casters normally have been positioned at the margins of the bedf-rame so that it is possible to bump such casters when walking around either the foot or the head of a bedframe.

It is the general object of the present invention to provide a novel, improved type of bedframe which is of relatively light but yet sturdy construction. 1

Another object of the invention is to provide a relatively inexpensive, easily assembled 'bed frame wherein caster sockets are provided that are alignedwith the vertically extending central axis of the caster support member; I 1

A further object of the invention is toprovide a bedframe which can .be shipped in a disassembled, compact package but which readily can be assembled to provide a solid bedframe.

Still another object of the invention is to provide a bedframe wherein the caster receiving sockets are laterally inwardly offset with relation to the margins of the bedframe.

The foregoing and other objects and advantages of the invention will be made more apparent as the specification proceeds.

For a better understanding of the invention reference should be had to the accompanying drawings, wherein: a

These bedframes usually have 11 Claims. (01. 5-202) 2 Fig. 1 is a plan of a principles of the invention;

Fig. 2 is a fragmentary enlarged plan of one corner construction of the bedframe of Fig. 1;

Fig. dis a side elevation of the portion of bedframe shown in Fig. 5; and

on line the Fig. '7 is a vertical section taken on line l-1 of Fig. 6.

To simplify correlation panying specification and the drawings, corresponding vnumerals are'used to refer to corresponding parts used in the drawings and specification.

The details of the drawings show that a frame I0 is provided, which frame It is usually made from metallic components. This frame includes a pair of side rails ll and I2 which usually are formed in the shape of angles that have one substantially horizontally disposed leg and one vertically upwardly extending leg. These side rails II and [2 each carry adjacent each end thereof a cross rail; or cross rail section. l3. Preferably the. cross rails:l3 are pivotally engaged with the side .rails. H and I2 by means of rivets I4 so that the cross rails l3 are positioned flush against the lowersurfaces of the side rail and are pivotal with relation thereto. Usually each cross rail section l3 extends substantially halfway across the bedframe NJ to. be made from the cross rails and side rails. of the invention. Each cross rail usually is in telescoped engagement with a cor-, responding crossrail positioned on a similar end of the other side rail of the bedframe and clamps 15 are provided for engaging with the telescoped portions of the cross'rails for retaining them in a desired position so as to form a bedframe 1| 0 of desired width.

As an importantfeature of the present lnven tion, a reinforcing angle I6 is associated with each cross rail l3 adjacent the end thereof which is in engagement with the side rail that posi tions such cross, rail. These reinforcing angles I6 are usually made from metal and are of right angular shape in cross section with one leg of the angle I6 being substantially horizontally disposed and being flush against, or abutted against the lower surface of the side rail, whereasa vertically extending leg of the angle I6 is in each ine stance downwardly extending and is also flush up against, or abutted against a vertically downwardly extending leg of the cross rail with which such reinforcing angle is associated. As hereinafter explained in more detail,.the reinforcingangles in every instance form ,a .unitrwith-the' bedframe embodying the a between the 'accom- Y cross rails-'witlriwhich they are'associated; Thus: in order to position the cross rails in desired substantially normal relationship to the side rails I I and I2, bolts IT, or other means, usually remov-- able, engage with the side rails. II. and I1 and with each reinforcing angle Ili'in the substan.-'- tially horizontally extending legs thereof." Thus these bolts I'I will, in combinationiwithitherivets:

I4, secure the cross rails I3 inc/desired fixed-re lationship to the side rails and willprovideabem frame of desired shape and of sturdy construc-- tion. By use of the particular type of side. rail: and cross rail construction referred to hereinbefore, it is possible to hold the cross rails-I 3- am ally inwardly of the bedframe so that they at least substantially coincides with; the side:. rails positioning same. Hence therzbedf rameifl caneasily' be shipped: in: aiknockdow-m. compact condition but yetthe components. oil the: bedframecan: easily be. assembled. in operative: relationship when the bedframe is to be assembled;v Theihea'dsit of the bolts: I 1 may be rounded 'and'substantially flush with the surfaces of the side rails.

Figs; 2-4 of thedrawings showa salient component of the frame and; this relates tof the provision of a: pair'of socket, or caster socket plates I8 and I9. A pair ofsuch socket 'plates. I8 and I9 are associatediwith. each assembly of a cross rail and a reinforcing angle.

The caster positioning means include a substantially U-shaped in section frame I3I that is in overlying engagement with the dependent legs of the cross rails H3 and reinforcing angles H5 and is suitably secured theretaas bywelding. Fig. 5 best shows that the frame I3'I extends laterally from the dependent legs ofthe reinforcing angles and cross rails in both directions-in order to have more rigid relationship therewith since the upper end of the frame I3'I normally abuts against the substantially: horizontally directed leg provided on the cross rails and reinforcing angles. A caster engagingsocket I32 is provided in a socket plate I33 that is positioned within the frame HM and secured: thereto in; any desired manner, such .as welding; A. suitable caster. I23 is shown. engaged. with. the-socket I 32'provided in the socketplate: I33.

From the foregoing; it will be seen thata' novel type of abedframe has been provided wherein. thefra-meacomponents can easily'beshipped in a; disassembled condition but which components; are. readily-adapted to be secured in a: fixed operative-association with each other. This bed-=- frame ismadefrom substantially conventional. members since usually both the siderails and: cross-rails-can be formed from lightweight metallic angles of conventional construction. These; lightweight frame components can easily and in-- expensively. be assembled to produce; asturdy:- frame that cannot be easily distorted. The.- only, operations required; in assembling; a bedframeoil the invention for. use would be to engage: the;

bolts ll with the bedframe and to secure; thee.

clamp. I5- to thecrossv rails. The special reinforceing means used do not interfere-with lateral adjustment of the frame and they also permit the; casters. to bep-ositioned laterally inwardly of the: frame. Hence-it is submitted thattheobjects. of. the invention have been achieved- While-several complete embodiments of the in. vention have been disclosed herein, it will be appreeiated that modifications of these particularembodiments of the-invention may beresorted to without departing from thescope of the inven--- tion as defined by the. appended claims.
